Wheel Bearings

The rear wheel bearing and wheel hub of this vehicle are a one piece sealed unit or hub and bearing unit type assembly. No adjustments are possible.

The center of the hub and bearing is splined to match the axle halfshaft.

The wheel mounting studs used to mount the tire and wheel to the vehicle are the only replaceable components of the hub and bearing. Otherwise, the hub and bearing is serviced only as a complete assembly.

Removal & Installation

Before servicing the vehicle, refer to the Precautions section.

Raise and support vehicle.

Remove wheel mounting nuts, then tire and wheel assembly.

While a helper applies brakes to keep hub from rotating, remove hub nut from the halfshaft.

NOTE

In some cases, it may be necessary to retract caliper piston in its bore a small amount in order to provide sufficient clearance between shoes and rotor to easily remove caliper from knuckle. This can usually be accomplished before guide pin bolts are removed, by grasping rear of caliper and pulling outward working with guide pins, thus retracting piston. Never push on piston directly as it may get damaged.

Remove two bolts securing disc brake caliper adapter to knuckle.

Remove disc brake caliper and adapter from knuckle as an assembly. Hang assembly out of way using wire or a bungee cord. Use care not to overextend brake hose when doing this.

Remove any clips retaining brake rotor to wheel mounting studs.

Slide brake rotor off hub and bearing.

Loosen each hub and bearing mounting bolt a turn or two at a time while pulling outward on hub and bearing to avoid bolt contact with halfshaft outer joint. Once removed from threads in hub and bearing (but not knuckle), allow bolts to stay in and protrude through knuckle and brake support plate to keep brake support plate in place when hub and bearing is removed.

Slide hub and bearing off knuckle and halfshaft.

To install:

NOTE

Before installing hub and bearing on end of axle halfshaft, ensure isolation washer is present on end of halfshaft. Inspect washer making sure it is not worn or damaged. Washer can be installed in either direction on shaft.

Position hub and bearing bolts though rear of knuckle and parking brake support just enough to hold support in place as hub and bearing is installed.
